Brabender Loss-in-Weight Feeders
Loss-in-weight feeders from Brabender Technologie GmbH & Co. KG are capable of reliably and accurately metering good to extremely poor flowing bulk ingredients (powders, flakes, chips, fibers, etc.). This is made possible by a variety of feed mechanisms selected in accordance with the respective ingredient (single screws, twin screws, vibrating trays, etc.), efficient agitation techniques like paddle-massaged flexible polyurethane hoppers ("FlexWall®" and "FlexWall®Plus" feeders) or stirring agitators, high resolution digital weighing systems and sophisticated controls.
The Brabender FlexWall®20 feeder is the youngest and smallest member in the FlexWall® feeder family. Just like all other well known feeders from this product line, their "little brother" is also equipped with a polyurethane hopper massaged by two external paddles providing real mass flow of ingredient. The feeder is capable of metering even poor flowing ingredients at low feed rates of just a few kilograms per hour. The feeder is easily disassembled without tools for wet or dry cleaning. The screw tube is held in place by a quick clamp, and the molded polyurethane hopper fits easily on the housing which is secured by latches allowing it to be lifted off for full access to all internal components. The screw and the paddles are driven by a brushless DC motor with an integrated speed controller. Combined with a hightech weighing system the feeder completes the Brabender line of loss-in-weight feeders.
Brabender loss-in-weight feeders are found in bulk ingredient processing industries world-wide, for instance in compounding, extrusion and mixing processes in the plastics industry.
